[PATCH v3 0/9] Add support for i.MX94 DCIF

[Laurentiu Palcu <laurentiu.palcu@oss.nxp.com>]

Hi,

This patch-set adds support for the i.MX94 Display Control Interface.
It depends on Peng Fan's DTS patch [1] that was not yet merged. Also, it
needs the BLK CTL changes [2] that I spinned off from v2 in a different
patchset.

Also, included in the patch-set are a few extra patches that the DCIF
driver depends on for functioning properly:
 * 1/9 - 3/9 : add support for i.MX94 to fsl-ldb driver. It also
			   contains a patch (2/9) from Liu Ying that was already reviewed
			   and was part of another patch-set ([3]), but was never merged;

v3:
 * Removed the BLK CTL patches and created a separate patch set [2] for them;
 * Collected r-b tags for 1/9, 2/9, 3/9 and 9/9;
 * Removed the DCIF QoS functionality until I find a better way to
   implement it through syscon. QoS functionality will be added in
   subsequent patches. Also, used devm_clk_bulk_get_all() and used
   dev_err_probe() as suggested;
 * Addressed Frank's and Krzysztof's comments on the DCIF bindings;
 * Addressed Frank's comments on dtsi and dts files;
 * Added a new binding patch, 6/9, for adding 'ldb' optional property to
   nxp,imx95-blk-ctl.yaml;

v2:
 * reworked the BLK_CTL patch and split in 2 to make it easier for
   review;
 * split the dts and dtsi patch in 2 separate ones;
 * addressed Frank's comments in DCIF driver;
 * addressed Rob's comments for the bindings files;
 * addressed a couple of checkpatch issues;

Thanks,
Laurentiu
